can't start tomcat in hpunix and tomcat4.1.29

[dragon ji]

I download jakarta-tomcat-4.1.29.tar.gz and decompress it in my hpunix,
I can't find jdk for hpunix at java.sun.com,so I use websphere-hp's jdk,set JAVA_HOME = $websphere-home/java:.
then I execute ./catalina.sh run,but I get exception information as followed:

 [ERROR] Digester - -Begin event threw exception <sun.misc.InvalidJarIndexExcepti
on: Invalid index!>sun.misc.InvalidJarIndexException: Invalid index!
